This document discusses finite state machine (FSM) design. It begins by motivating FSMs as a generalization of counters where outputs are a function of state rather than just the state itself. FSMs are used to implement circuits that control other circuits and make decisions based on their state and inputs. The chapter then provides an overview of the concepts to be covered, including defining the FSM, representing state transitions, Moore and Mealy machines, and using word problems and case studies. It describes the basic six-step design process and covers the concept of the state machine in more detail, including timing, state diagrams, and communicating between state machines.

In Actors system, we can change State or Behaviors during runtime in actors. There are multiple ways for changing behaviors like conditional based and Hotswap but Finite State Machine(FSM) is the cleanest way. If we have finite number of state in our system then FSM is the good practice.
It is a mathematical modelling of computation that is extensively used for designing both computer programs as well as sequential logic circuits and can be perceived as an intellectual machine in one of a finite number of states.

Finite State Machines are overlooked at best, ignored at worst, and virtually always dismissed. This is tragic since FSMs are not just about Door Locks (the most commonly used example). On the contrary, these FSMs are invaluable in clearly defining communication protocols – ranging from low-level web-services through complex telephony application to reliable interactions between loosely-coupled systems. Properly using them can significantly enhance the stability and reliability of your systems.
Join me as I take you through a crash-course in FSMs, using erlang’s gen_fsm behavior as the background, and hopefully leaving you with a better appreciation of both FSM and erlang in the process.

Server to Cloud – convert a legacy platform to a micro-PaaS using Docker and related, containerization technologies
Video: http://vimeo.com/94556976
The talk will begin with how to setup a local Docker development environment (Windows or Mac OSX) as Docker runs atop Linux. The basics of Docker will be examined including how to use image repositories, and a brief description of available UI’s for managing Docker containers (Shipyard and DockerUI).
Next, example applications will be built for progressively more robust use cases and deployments; to demonstrate the power, flexibility and scalability of Containerization with Docker. The first example will discuss a simple two container model to encapsulate a database and application layer, which will lead to demonstration and discussion about more robust deployments that include features such as service discovery, automatic load balancing, and abstractions to simplify linking of containers. The context of the talk with be how Containerization enables architectural choice, scalability, and polyglot environments.
Docker and supporting technologies will be discussed to expose the multitude of supporting technologies within the ecosystem such as Flynn, Serf (makes or Vagrant), CoreOS, Deus, HAProxy and more.
Technologies that may be employed within containers during the demonstration include, Java, Scala, Akka, Docker, vert.x or node.js, memcached, mysql, mongo.
Definition of finite state automaton: computation. It is an abstract machine that can be in exactly one of a finite number of states at any given time. The FSM can change from one state to another in response to some external inputs; the change from one state to another is called a transition. A FSM is defined by a list of its states, its initial state, and the conditions for each transition.

SYNCHRONOUS SYSTEM
A synchronous system is a digital system in which the changes in the state of memory elements
are synchronized by a clock signal.
i.e, operations are coordinated under the centralized control of a fixed-rate clock signal or
several clocks.
DYNAMIC INDICATOR
dynamic(edge trigerred) inputs are sampled only when clock state changes .thsi type of input is
indicated on logic symbols by a small triangle (called as dynamic indicator) on the line where
input is given
REPRESENTATIONS OF FINITE STATE MACHINES (FSM)
EVENT/STATE TABLE
Several state transition table types are used. In general ,the combination of current state and input
shows the next state . The complete action\'s information is not directly described in the table and
can only be added using footnotes
UML STATE MACHINES
The Unified Modeling Language has a notation for describing state machines. UML state
machines overcome the limitations of traditional finite state machines while retaining their main
benefits. UML state machines introduce the new concepts of hierarchically nested statesand
orthogonal regions, while extending the notion of actions. UML state machines have the
characteristics of both Mealy machines andMoore machines. They support actions that depend
on both the state of the system and the triggering event, as in Mealy machines, as well as entry
and exit actions, which are associated with states rather than transitions, as in Moore machines.
SDL STATE MACHINES
The Specification and Description Language is a standard from ITU that includes graphical
symbols to describe actions in the transition:
SDL embeds basic data types called Abstract Data Types, an action language, and .

One reason we have a tendency to clock flip flops so there is not any chaos once the outputs of
flip flops area unit fed through some logic functions and back to their own inputs.
If a flip-flop\'s output is employed to calculate its input, it behooves North American nation to
possess orderly behavior: to stop the flip-flop\'s state from dynamical till the output (and
therefore the input) is stable.
This duration permits North American nation to create computers, that area unit state machines:
they need a current state, and calculate their next state supported the present state and a few
inputs.
For example, suppose we would like to create a machine that \"computes\" AN incrementing
four bit count from 0000 to 1111, and so wraps around to 0000 and keeps going. we are able to
do that by employing a four bit register (which may be a bank of 4 D flip-flops). The output of
the register is place through a combinatorial logic perform that adds one (a four bit adder) to
supply the incremented worth. This worth is then merely fed back to the register. Now, whenever
the clock edge arrives, the register can settle for the new worth that is one and its previous worth.
we\'ve AN orderly, certain behavior that steps through the binary numbers with none bug.
Clocking behaviors area unit helpful in different things too. typically a circuit has several inputs,
that don\'t stabilize at identical time. If the output is in a flash created from the inputs, then it\'ll
be chaotic till the inputs stabilize. If we have a tendency to don\'t need the opposite circuits that
rely on the output to examine the chaos, we have a tendency to create the circuit clocked. we
have a tendency to permit a generous quantity of your time for the inputs to settle and so we have
a tendency to enlighten the circuit to just accept the values.
Clocking is additionally inherently a part of the linguistics of some forms of flip flops. A D flip
flop can not be outlined while not a clock input. while not a clock input, it\'ll either ignore its D
input (useless!), or just copy the input the least bit times (not a flip-flop!) AN RS flip-flop does
not have a clock, however it uses 2 inputs to regulate the state that permits the inputs to be \"self
clocking\": i.e. to be the inputs, in addition because the triggers for the physical change. All flip
flops would like some combination of inputs that programs their state, and a few combination of
inputs lets them maintain their state. If all mixtures of inputs trigger programming, or if all
mixtures of inputs area unit unnoticed (state is maintained), that\'s not helpful. currently what\'s a
clock? A clock may be a special, dedicated input that distinguishes whether or not the opposite
inputs area unit unnoticed, or whether or not they program the device. it\'s helpful to possess this
as a separate input, instead of for it to be encoded among multiple inputs.

Tzu-Li (Gordon) Tai - Stateful Stream Processing with Apache FlinkVerverica
As Apache Flink continues to push the boundaries of stateful stream processing as an integral part of its past releases, increasing numbers of users are starting to realize the potential of stateful stream processing as a promising paradigm for robust and reactive data analytics as well as event-driven applications.
This talk aims at covering the general idea and motivations of stateful stream processing, and how Flink enables it with its powerful set of state management features and programming APIs. In addition to that, we will also take a look at the recent advancements related to Flink's state management and large state handling that were driven by our team at data Artisans team in the latest version 1.3 (expected release by end of May / early June).
Unified stateful big data processing in Apache Beam (incubating)Aljoscha Krettek
Apache Beam lets you process unbounded, out-of-order, global-scale data with portable high-level pipelines, but not all use cases are pipelines of simple “map” and “combine” operations. Aljoscha Krettek introduces Beam’s new State API, which brings scalability and consistency to fine-grained stateful processing while interoperating with Beam’s other features such as consistent event-time windowing and windowed side inputs—all while remaining portable to any Beam runner, including Apache Apex, Apache Flink, Apache Spark, and Google Cloud Dataflow. Aljoscha covers the new state and timer features in Beam and shows how to use them to express common real-world use cases in a backend-agnostic manner.
Examples of new use cases unlocked by Beam’s new mutable state and timers include:
* Microservice-like streaming applications such as new user account verification and digital ordering
* Complex aggregations that cannot easily be expressed as an efficient associative combiner
* Output based on customized conditions, such as limiting to only “significant” changes in a learned model (resulting in potentially large cost savings in subsequent processing)
* Fine control over retrieval and storage of intermediate values during aggregation
* Reading from and writing to external systems with detailed management of the nature and size of requests
